I'm assuming it already exists due to the existence of pages like https://musicbrainz.org/tops/mb_top_stuff.html and https://stats.metabrainz.org, I'm just not positive of it. :)

Even if it's not collected though, it's data that they at least already have the ability to collect by simply flipping a switch, as opposed to spinning up a whole new ListenBrainz service and hoping it gains traction.

Oh, and the mp_top_stuff.html page was created less than a week ago.

You're absolutely right that we could, in theory, have that data, but we do not currently. Not in any usable form (for this purpose) anyway.

Note that ListenBrainz may be used for getting "popularity" metrics, but that is not its intended goal.
